I have a dual air Thomas model 2650c e34-925F
This is my second one and both of them after about 2 years stop pumping enough air to push air through the diffusers. Any ideas why this is happening or what I could do to check to get them working back to original output?
Any info would be much appreciated!

If I had to guess, I would say the piston cups are worn. The 2650 series are fairly simple and straightforward to rebuild, and parts are readily available. Here's a how-to link. http://forums.pondboss.com/ubbthreads.php?ubb=showflat&Number=390615
"Forget pounds and ounces, I'm figuring displacement!"
If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.

I agree with Sprkplug. As long as the motor runs, the pumps probably just need rebuilding. As suggested check the piston cups or one or both of the flipper valves maybe are broke or out of alignment. Let us know what you find.
